To a solution of 6-(4,5-difluoro-2-(2-iodo-3-methyl-benzoylamino)-indan-2-carboxylic acid ethyl ester (386) (2.55 g, 5.25 mmol) and 2-methyl-1-propenyl boronic acid pinacol ester (364 mg, 10.5 mmol) in dioxane (100 mL) is added dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium (II) dichloromethane adduct (350 mg, 8.2% mmol) and 2M aqueous solution of K2CO3 (7.87 mL, 15.75 mmol). The resulting reaction mixture is filled in with N2, heated to 100° C. and stirred continuously for 6 h. Reaction mixture is filtered and concentrated in vacuo, and the resulting residue is purified by flash column chromatography (12 g silica gel, gradient elution: 0%-50% EtOAc in heptane) to give a pure product (387) as light brown solid (1.24 g, 57%).
